The adjacent sides of a parallelogram are in the ratio 3:7 and its perimeter is 100cm. Find the sides of the parallelogram.

Answers (1)

perimeter of parallelogram = 100

Let the adjacent sides of the parallelogram are 3x and 7x.
We know that, the opposite sides of a parallelogram are equal.
Hence, the other two adjacent sides are also 3x and 7x.

3x + 7x + 3x + 7 x =100

x = 5
